The maximum cable length supported by the CY7C65620-56LTXAT is 3 meters (10 feet) for USB 2.0 and 1 meter (3.3 feet) for USB 3.0, assuming a good quality cable and a well-designed system.
To configure the CY7C65620-56LTXAT for USB 3.0 operation, you need to set the USB3_EN pin high and ensure that the VBUS pin is connected to a 5V power source. Additionally, you may need to adjust the signal termination and routing to meet USB 3.0 signal integrity requirements.
Yes, the CY7C65620-56LTXAT is backward compatible with USB 2.0 and USB 1.1 devices. However, the device will operate at the lower speed of the connected device. For example, if a USB 2.0 device is connected, the CY7C65620-56LTXAT will operate at USB 2.0 speeds.
The power consumption of the CY7C65620-56LTXAT depends on the operating mode and the speed of the connected device. In USB 3.0 mode, the typical power consumption is around 350 mA. In USB 2.0 mode, the typical power consumption is around 150 mA.
The CY7C65620-56LTXAT has an internal overcurrent protection (OCP) feature that can be enabled by connecting the OCP_EN pin to VCC. The OCP threshold is set to 1.5A by default, but can be adjusted by connecting a resistor to the OCP_ADJ pin.
